Daim ntawv no tau tshawb xyuas cov ntsiab lus tseem ceeb thiab cov ntaub ntawv hauv cov ntawv luam tawm hauv kev luam ntawv thiab kev nyab xeeb, thiab npaj cov tswv yim tshwj xeeb rau kev tswj cov khoom tsim kev puas tsuaj thiab kev txhim kho lub chaw luam tawm.
Ntsuab ib puag ncig tiv thaiv tau los ua cov ntsiab lus tseem ceeb ntawm lub xyoo tshiab. Qhov teeb meem ntawm greening nyob rau hauv niaj hnub luam tau los ua ib qho teeb meem loj uas hinders sustainable kev lag luam luam. Nws yog ib qho tseem ceeb rau pib ntsuab tej yaam num, tsim cov khoom ntsuab, thiab hloov kho raws li kev cai ntawm ib puag ncig. Nrog rau kev tshwm sim los ntawm ntau cov khoom ntsuab, nws yuav tsis muaj lub hnab ntim zoo dua thiab ntau dua cov ntaub ntawv luam ntawv ntsuab thiab cov ntawv luam tawm. Flexographic luam ntawv yog ua raws li qhov xav tau ntawm lub sij hawm thiab nws yog qhov nce dua qhov kev lag luam ntsuab dua hauv tsev thiab nyob sab nraud.
Flexographic luam ntawv, yav tas los hu ua "aniline printing", yog lub npe tom qab luam ntawm volatile inks ua nrog aniline dyes. Vim kev mob aniline yog lom, nws cov ntawv luam tawm yog zoo heev. Nrog rau kev siv cov tshuab ua flexographic printing tshuab thiab qhov nce ntxiv ntawm daim ntawv thov, thiab kev nce qib ntawm non-toxic, non-residual submersible, environmentally friendly water-based inks, Uv roj thiab qaug dej qaug cawv, nws yoog rau kev tiv thaiv ib puag ncig thiab ntsuab ntim. Yuav tsum tau, yog li nws tuaj yeem tsim tau sai. Txawm tias cov flexographic luam tau zoo los ua kom muaj kev phom sij zoo rau lwm txoj kev luam tawm, nws tsuas yog siv cov flexo luam ntawv xwb, tsis muaj teeb meem li cas siab tshaj technology, txheej txheem thiab cov khoom siv, nws tsis tiav, tsis yog polluting. Yog li, ua kom tiav greening ntawm flexographic luam ntawv, ntxiv rau kev nrhiav kev ua kom tiav ntawm cov ntaub ntawv thiab cov txheej txheem, nws yog qhov tsim nyog rau cov neeg tsav tsheb thiab cov tswj xyuas kom ua tau ntau dua cov kev siv zog los txo cov kev ua kom tsis zoo. Muaj ntau yam tseem ceeb uas cuam tshuam rau ib puag ncig ntawm kev luam ntawv luam tawm hauv qab no.
Environmental impact factors nyob rau hauv lub phaj ua txheej txheem
Kev Txhim Kho
Ib qho tseem ceeb ntawm lub cheeb tsam uas cuam tshuam cov phaj ua txheej txheem yog daim ntawv thov ntawm tus tsim tawm. Cov phaj uas tau yooj yim tau ua tiav ib txoj kev loj hlob los ntawm cov phom rubber rau ib lub phom heev, thiab nws tau raug siv los ntawm nws tus yam ntxwv zoo. Lub tshuab ua yoojyim ua ywj pheej yog ua tiav hauv lub tshuab tshwj xeeb stenciling. Kev tsim tshuaj feem ntau yog siv cov roj (hydrocarbon) hnyav (trinitroethylene) ua lub ntsiab hnyav, tab sis cov tris-ethylene yog lom, thiab nws cov volatility muaj zog heev. Nco ntsoov tias cov kab hlau uas muaj tertiary ethylene vapor nyob hauv cov huab cua tsis pub tshaj cov tshuaj lom. Ntxiv mus, thaum peb lub atmospheres ntawm ethylene coexist nyob rau hauv muaj teeb, cua, thiab noo noo, lawv decompose los tsim teeb meem atmospheric hydrogen acid roj, ua rau hlau corrosion. Yog li ntawd, nyob hauv tus txheej txheem ntawm kev siv, yuav tsum muaj cov cuab yeej tshwj xeeb. Cov khoom siv nws tus kheej tuaj yeem siv tau mus ua dua qub thiab nws nyiam dua hauv daim ntawv kaw. Ib qho kev qhia zoo dua yog los tsim ib qho hnyav uas tsis tshua muaj kev phom sij es tsis txhob muaj tertiary ethylene.
2. Cov txheej txheem debonding
De-bonding yog kev siv lub teeb lossis tshuaj txoj kev siv lub teeb tsa. Lub hom phiaj yog los tshem tawm cov nplhaib ntawm lub phaj ntawm lub phaj thiab txhim kho lub peev xwm ntawm cov hmoov.
1 txoj kev tshuaj
Cov txheej txheem muaj xws li cov nram qab no: muab cov ntawv pov tseg rau hauv ib qho kev sib txuas ntawm cov kua nruab nrab ntawm kev kho tshuaj, kev siv tshuaj thiab kev kho kom zoo nkauj (aqueous bleaching hmoov) thiab kev kho mob (hydrochloric acid thiab aqueous solution of australis) hais tias ob lub daws yog tsis tshua muaj siab ntev rau qhov chaw, yog li nyob rau hauv tus txheej txheem ntawm drilling, qhov no muaj txoj kev maj tsis coj rau cov neeg.
2 txoj kab teeb pom kev zoo
Qhov no yog ib txoj kev siv, uas tau ua tiav los ntawm kev daws teeb meem hauv Australia nrog ultraviolet c (UV-c lub teeb qhov chaw). Piv nrog rau thawj txoj kev, qhov chaw ua kom tsis zoo los ntawm txoj kev tsis pom kev los ntawm txoj kev taws teeb pom kev zoo dua, tab sis nws yuav tsum tau sau tseg tias cov tshuaj tom qab cov hluav taws xob qis hauv qhov kev teeb tsa tsis zoo rau qhov chaw, thiab cov dej khib nyiab yuav tsum muab pov tseg .
Nyob rau ntawm LabeExpo hauv Chicago hauv lub Cuaj Hli Ntuj xyoo 2000, DuPont tau qhia txog Sally Express System, ib qho kev ua lag luam ntawm cov lus teb. Tus essence yog ib cov txheej txheem ua haujlwm kub, thiab tag nrho cov txheej txheem kom qhuav.
Vim tias tsis muaj qhov hnyav, nws yuav tshem tawm cov teeb meem muaj kuab paug hauv cov kuab tshuaj. Tsis tas li ntawd, nws kuj ua tau kom cov phaj ua lub sij hawm, thiab cov txheej txheem cov txheej txheem kuj tseem ceev tsis qhuav.
Environmental factors in number case applications
Tam sim no, roj yog qhov chaw muaj kev ua qias tuaj hauv kev lag luam luam. Txhua xyoo cov roj hauv lub ntiaj teb tau mus txog 3 lab tons. Ntiaj teb no emissions ntawm VOCs (organic volatiles) tshwm sim los ntawm cov inks tau mus txog pua pua txhiab tons ntawm ib xyoo. Cov organic volatiles no tsim tau ib qho kev ua kom tsob nroj loj dua cO2, thiab tsim cov oxides thiab cov yeeb yaj kiab uas muaj yees duab ntawm cov huab cua nyob rau hauv lub cheeb tsam, uas tau tshwm sim thoob plaws kev txhawj xeeb nyob rau ntau thaj chaw. Ntawm ntau txoj kev luam ntawv, tsuas yog cov xaim hluav taws xob ntsuab ntawm cov ntaub ntawv luam tawm-dej-raws li tau siv cov ntawv luam tawm ntau xwb. Tus number case Uv thiab tus cwj pwm-dissolving number case tshaj tawm qhia thawj ob.
Dej raws li kua
Qhov loj tshaj plaws ntawm dej-raws hauv qab yog tias nws txo cov emission ntawm lub cev (organic volatiles), li no tiv thaiv kom txhob muaj pa phem los ntawm kev txhim kho cov chaw luam ntawv thiab kev txhawb nqa neeg ua haujlwm. Nws tuaj yeem ua kom tshem tawm qhov raug mob ntawm tej yam tshuaj lom thiab cov khoom teeb meem hauv qhov hnyav hauv tib neeg lub cev thiab cov pa phem ntawm cov khoom ntim khoom, thiab txhim kho txoj kev nyab xeeb tag nrho. Nws yog tshwj xeeb tshaj yog tsim rau ntim thiab luam ntawv cov khoom nrog nruj huv chaw kho mob xws li zaub mov, dej haus thiab tshuaj. Tsis tas li ntawd xwb, nws tsuas yog txo cov kev pheej hmoo ntawm hluav taws thiab stagnation los ntawm cov hluav taws xob thiab hluav taws xob uas muaj zog, tiam sis kuj txo cov ntxhiab tsw ntxiv nyob rau ntawm cov ntawv luam tawm.
Raws li tib neeg kev hu xov tooj rau kev tiv thaiv ib puag ncig yog nce siab dua thiab siab tshaj, qhov xwm txheej ntawm cov dej hauv lub cev yuav ua rau ntau dua, thiab nws txoj kev siv yuav tsis tshua muaj ntau dua. Yog li ntawd, peb yuav tsum tswj cov yeeb yam ntawm cov dej-raws li hauv ntau tshaj tawm kom qis qis dua tej chaw muaj kuab paug. Txawm hais tias tus cwj mem raws dej tuaj yeem txo cov kev tso kawm ntawm VOC, peb cia siab tias tswj fais fab no mus rau qib qis. Nyob rau hauv qhov kev pab cuam tu tshuab hauv California tau siv ntau xyoo dhau los, cov ntsiab lus ntawm cov organic volatiles hauv aqueous inks yuav tsum tsis pub ntau tshaj 3%. Tsis tas li ntawd, ntau tus neeg siv thiab cov lag luam muaj kev txwv thiab yuav tsum rau cov hlau hnyav uas muaj f nyob hauv cov dej hauv qab. Uas yog hais tias, hauv kev tsim cov dej-raws li cov phev, nws yog ib qho tsim nyog los xaiv cov pigments kom tshem tawm cov pigments nrog theem siab ntawm cov hlau ions loj.
2.Kev number case
Uv hluav taws xob curing khoom (xws li Uv inks thiab Uv varnishes) yog hu ua "green industrial technologies tshiab rau lub 21st century" rau lawv cov kev ua haujlwm siab, kev txuag hluav taws xob, tsis muaj hnoog tsis muaj zog, tsis muaj pa phem thiab kev ua haujlwm zoo. Lawv txoj kev nyab xeeb tau ua los ntawm US Environmental Protection Agency pom zoo. Hauv 10 lub xyoo dhau los, daim ntawv thov UV roj thiab UV coatings tau ua nrov nrov. Raws li kev txheeb xyuas, txoj haujlwm luam tawm UV ntawm US lub hauv xyoo 2001 tau muaj 3,500 tons.
UV cwj mem tsis yog tsuas yog roj-dawb kev nyab xeeb, tab sis kuj muaj ntau yam khoom zoo heev. Piv txwv li, nws tsis yooj yim rau kev muab tshuaj, meej dots, ci ntsa iab thiab kaj siab, tshuaj lom neeg muaj zog, thiab tsawg npaum li cas. Kev nce qib thiab daim ntawv thov ntawm UV roj tsis yog tsuas yog siv rau kev tiv thaiv ib puag ncig, tab sis kuj pom zoo rau kev txhim kho ntawm cov flexo luam tawm khoom, thiab txhawb nqa ntxiv kev loj hlob ntawm flexographic printing tshuab.
Los ntawm cov kev xav ntawm ib puag ncig tiv thaiv, UV number case tiag tiag yog ib tug zoo kawg thiab number case. Nws yuav tsum tau sau tseg tias feem ntau UV cov khoom yuav pom tau tias tawv nqaij voos ua ntej lawv qhuav. Txawm li cas los xij, vim tias lawv tsis tshua muaj zog, cov khoom no tuaj yeem txo cov teeb meem xws li yog lawv tuav cov cwj pwm ntawm hnab looj tes thiab kev tiv thaiv qhov muag thaum lub sijhawm ua haujlwm. Tsis tas li ntawd, nws yog ib qho tsim nyog yuav tau muab cov khoom tso rau yav tom ntej vim hais tias hom qub ultraviolet number case emits oxygen.
Tej kev cuam tshuam ntawm anilox rau cov menyuam
Hauv flexographic luam ntawv, anilox yob yog ib qho tseem ceeb heev nyob rau hauv txoj kev hloov qis dua. Qhov nws saum npoo yog them zoo kawg nkaus cov hlwb, los ntawm kev uas tus number case yog hloov, thiab tus number case clogs yog pob tshab. Mob taub hau heev hauv luam ntawv. Feem ntau, cov mesh ntsaws yog los ntawm qhov blockage ntawm cov roj uas muaj roj uas muaj cov kabmob anilox thaum ua haujlwm. Vim li no, tus menyuam yuav tsum tau muab cov tshuaj tua kabmob (anilox) rau hauv cov sijhawm thaum luam ntawv.
Cov kev tu tsev feem ntau muaj hom nram qab no:
1. Muaj zog ua kom muaj kev txhuam cov tshuaj ntxuav vaj tse
Siv cov tshuaj txhuam tu corrosive (feem ntau yog alkaline tov) tusyees nyob rau ntawm qhov npoo anilox. Yog tias tsim nyog, qhwv ib txheej ntawm cov yas rau saum npoo ntawm lub pob yas txha caj dab los tiv thaiv cov kua los ntawm cov evaporating. Qhov anilox yob yog ablated rau 1-48 teev. Tom qab tus cwj mem kua muag muag tag, cov tshuaj tua kab yas yog ntxuav los ntawm kev siv tshuaj ntxuav tes los yog dej cawv (tsis yog siv acidic xws li acetic acid). Xws li txoj kev ntxuav vaj tse muaj kev tu zoo, tab sis muaj qee qhov kev kub ntxhov rau ntawm tus menyuam anilox thiab ua rau muaj kev ua kom tsis zoo.
2. Dav hlau ntxuav dav hlau
Txau qhov ci cov dej qab softening tu qhov nruab nrab rau saum npoo ntawm anilox yob so ntawm tus cwj pwm (solidified) rau kev ntxuav. Ci dej qab zib yog yooj yim rau yaj thiab tsis muaj kuab lom. Thaum nws nrog lwm cov tshuaj sib tsoo, nws cov nplais ua tau yooj yim tawg thiab yuav tsis ua kom puas tsuaj rau saum npoo anilox thiab phab ntsa ntawm tus cwj mem. Vim li no, txoj kev ntxuav tsev no muaj kev zoo huv thiab muaj kev nce qib thiab siv tus nqi.
3. Ultrasonic ntxuav txoj kev
Cov menyuam yaus retorted raus hauv ib chav ultrasonic tu dej uas muaj tshuaj ntxuav tu. Thaum tu, tus menyuam anilox qeeb qeeb. Kev hloov cov khoom siv zaus uas yuav kis tau suab nrov hauv lub pas dej ua ke pib ua hauj lwm, ua rau kev daws teeb meem thiab tsim cov npuas, ua rau ua rau sab hauv ploj mus tsis tu ncua. Ntev quab yuam ejects tus number case ntawm lub xov tooj ntawm tes thiab ntws tawm nrog kev daws teeb meem. Hom no kuj yog ib tus phooj ywg zoo heev.
Nws tuaj yeem pom los ntawm cov saum toj no peb txoj kev uas tom kawg ob txoj kev muaj feem cuam tshuam rau qhov chaw, thiab qhov kev ntxuav thib peb muaj kev ywj pheej thiab cov txheej txheem nyuaj. Yog li ntawd, txhua lub tshuab luam ntawv yuav tsum xaiv qhov tsim nyog anilox tu tus qauv nrog rau qhov xwm txheej ntawm lub hoobkas.
Rov qab kho qhov system
Cov txheej txheem ub txuag txuag thiab cov ntaub ntim khoom tu (rau kev rov ua dua thiab rov qab siv dua tshiab) tau tsim tsa ntau lub teb chaws.
Recycling txhais tau hais tias rov qab siv dua thiab kev ua haujlwm ntawm ib yam khoom lossis ib feem ntawm nws hauv lub cev. Cov kab mob hauv tsev no ua rau cov ntaub ntawv nyhav nyhav thiab txuag cov khoom siv thiab cov khoom pov tseg los ntawm qhov no txhais tau tias, thiab txo qhov kev phem ntawm qhov chaw nyob.
Los ntawm kev soj ntsuam saum toj no, nws yog ib qho ua tau kom tswj tau ob peb yam tseem ceeb uas cuam tshuam rau ib puag ncig thiab kev nyab xeeb ntawm cov luam ntawv loj. Ntawm chav kawm, cov kev tiv thaiv no tsis yog cov niaj hnub siv.
